使用 JavaScript 在字符串中获取撇号
本教程解释了如何使用 JavaScript 通过用单引号和双引号将字符串括起来来获取字符串中的撇号。
var message = "Hi, Let's start reading if you are free!";
console.log(message);
输出：
"Hi, Let's start reading if you are free!"
假设字符串在字符串中的多个位置有撇号； 我们还能用双引号吗？可以，请看下面的例子。
var message = "I can start reading soon when I'll be free from this project, but it doesn't seem to happen.";
console.log(message);
输出：
"I can start reading soon when I'll be free from this project, but it doesn't seem to happen."
var message = "Hi, Let\'s start reading if you are free!";
console.log(message);
输出：
"Hi, Let's start reading if you are free!"
你可能会想，如果我们使用转义字符，我们可以将字符串用单引号括起来而不影响结果吗？是的当然。
var message = 'Hi, Let\'s start reading if you are free!';
console.log(message);
输出：
"Hi, Let's start reading if you are free!"
我们可以在字符串中任何需要的地方转义撇号。
var message = 'I\'ll start reading soon when I\'ll be free from this project, but it doesn\'t seems to happen.';
console.log(message);
输出：
"I'll start reading soon when I'll be free from this project, but it doesn't seem to happen."
